Double (lotto)
A daily 3- or 4-digit number that contains two of the same digit.
Examples: 122, 353, 1451, 3321. There are 90 boxed double combinations
in the three-digit game and one should show up every 4 days.
Since there are few double numbers, the payouts are usually
much higher. Four-digit doubles come up every 2.5 days and there
are 360 possible boxed combinations.
Double (general terms)
Select the teams or players you believe will win two separate
specified events or two parts of the same event, e.g.: Winners
of a rugby and league game, or the half and full time leaders
in the same game. All bets are placed prior to the first event.
